Description

Technical Field

[0001] This utility model relates to the field of polyurethane optical lens processing technology, specifically an adhesive coating device for encapsulating polyurethane optical lenses with PET film. Background Technology

[0002] Polyurethane optical lenses are high-refractive-index lenses made of polyurethane material. They possess high optical performance and impact resistance, making them suitable for high-prescription eyeglasses. A PET film is typically laminated to the surface of polyurethane optical lenses, usually using polyurethane adhesives. The PET film has a hardness of 3-5H, forming an "armor" layer on the lens surface, thus improving its abrasion resistance. Furthermore, the PET film has high light transmittance and low haze, maintaining clear image quality and true color reproduction without affecting light transmission.

[0003] To maximize the adhesion performance of polyurethane adhesives, the surface of the polyurethane optical lens needs to be cleaned before applying the adhesive to remove dust or impurities. Currently, lens cleaning and application are usually done separately: the lens surface is cleaned first, and then transferred to an application unit for adhesive application. However, it is difficult to guarantee that the lens will not re-adhere to dust during the transfer process. If dust re-adheres to the lens surface during transfer, it will reduce the adhesive strength after the adhesive is applied, causing the PET film to easily detach from the lens, thus shortening the lifespan of the polyurethane optical lens. Utility Model Content

[0004] The purpose of this invention is to provide an adhesive coating device for encapsulating polyurethane optical lenses with PET film, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adhesive coating apparatus for encapsulating polyurethane optical lenses with PET film includes: a lifting platform that can be lifted and lowered on a base, a mounting seat that is rotatably mounted on the lifting platform, and a mounting box that is also provided on the base;

[0007] The mounting box is equipped with a coating mechanism, which includes a cleaning component and a coating component. The mounting box is also equipped with a driving component, which cooperates with a trigger component on the lifting platform. When the mounting base rotates, the trigger component can drive the driving component to move, thereby driving the cleaning component and the coating component to move in the opposite direction.

[0008] The adhesive coating device for encapsulating polyurethane optical lenses with PET film as described above: the driving component includes a rotating rod rotatably mounted on a mounting box, the rotating rod being symmetrically fitted with two sets of sleeves slidably connected to the mounting box, the inner wall of the sleeves having protrusions, the protrusions being slidably disposed in fitting grooves opened on the rotating rod.

[0009] The adhesive coating apparatus for encapsulating polyurethane optical lenses with PET film as described above: the fitting groove includes a horizontal groove and a threaded groove formed on the rotating rod.

[0010] The adhesive coating device for encapsulating polyurethane optical lenses with PET film as described above: the cleaning component and the coating component are respectively disposed on two sets of sleeves. The cleaning component includes a plug rod fixedly connected to the sleeve. A second spring is sleeved on the plug rod. One end of the second spring abuts against the sleeve, and the other end abuts against a slider slidably disposed on the plug rod. A scraper is disposed on the slider.

[0011] The adhesive coating device for encapsulating polyurethane optical lenses with PET film as described above: the coating assembly includes a slide rod disposed on another set of the sleeve cylinders, a first spring sleeved on the slide rod, one end of the first spring abutting against the sleeve cylinder, and the other end abutting against a glue injection cylinder slidably disposed on the slide rod, and a coating roller brush rotatably mounted on the glue injection cylinder.

[0012] The adhesive coating device for encapsulating polyurethane optical lenses with PET film as described above: the triggering component includes a linkage structure and a transmission structure. The linkage structure includes a drive gear rotatably mounted on the lifting platform. The drive gear meshes with the toothed structure formed by the outer wall of the mounting base, and a fixed cylinder is coaxially arranged on the drive gear.

[0013] The adhesive coating device for encapsulating polyurethane optical lenses with PET film as described above: the transmission structure includes a transmission rod rotatably mounted on the mounting box, the transmission rod being inserted into the fixed cylinder, and the transmission rod being connected to a linkage rod rotatably mounted on the mounting box, the linkage rod being connected to the rotating rod through a bevel gear set.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By incorporating a drive unit, a cleaning component, and an application component, the drive unit rotates synchronously when the mounting base rotates. This allows the drive unit to simultaneously activate the cleaning and application components. In conjunction with the mounting base's upward movement, the cleaning component first contacts the lens body to scrape away dust and impurities from its surface. Then, the application component immediately applies adhesive to the cleaned lens body. The cleaning and application processes occur sequentially without manual intervention, thereby improving the encapsulation efficiency of the PET film on the lens body. Furthermore, while ensuring cleaning, the system guarantees the clarity of the lens body after the PET film is adhered, as well as the bonding strength of the adhesive, thus extending the lifespan of the lens body.

[0016] Furthermore, during the cleaning and application process, both the scraper and the application roller move outward in a spiral motion from the center of the lens. This motion trajectory ensures that the adhesive is evenly applied to the curved surface of the lens body. Under the action of the first and second springs, it is ensured that the scraper and the application roller can fully contact the curved surface of the lens body, thereby ensuring that the adhesive can be effectively applied.

[0026] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0027] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0028] Please see Figures 1-7 In this embodiment of the invention, an adhesive coating device for encapsulating a polyurethane optical lens with a PET film includes:

[0029] A lifting platform 3 is vertically mounted on a base 1, and a mounting base 5 is rotatably mounted on the lifting platform 3. For details, please refer to [link / reference needed]. Figure 1 , Figure 2 The aforementioned lifting platform 3 is connected to the base 1 via an electric telescopic rod 10, and the base 1 is also provided with an installation box 2. The electric telescopic rod 10 can change the distance between the installation seat 5 and the installation box 2, thereby facilitating the subsequent placement of the lens body 4 onto the installation seat 5.

[0030] In detail, the mounting base 5 is provided with six sets of positioning posts 501 equidistantly arranged along the circumferential direction on the side facing the mounting box 2. The outer wall of the positioning post 501 is provided with a rubber structure. When the lens body 4 is placed, the six sets of positioning posts 501 cooperate with each other to fix the lens body 4 on the mounting base 5.

[0031] Furthermore, a plug-in tube 14 is coaxially provided on the other side of the mounting base 5. The plug-in tube 14 is slidably connected to the drive rod 12 installed on the base 1. The drive rod 12 is controlled by the drive structure provided in the base 1, which can drive the plug-in tube 14 to rotate the mounting base 5.

[0032] Further, please refer to Figures 1-7 The mounting box 2 is provided with a coating mechanism, which includes a cleaning component and a coating component. The mounting box 2 is also provided with a driving component, which cooperates with a trigger component provided on the lifting platform 3. When the mounting base 5 rotates, the trigger component can drive the driving component to move, thereby driving the cleaning component and the coating component to move in the opposite direction.

[0033] The driving component includes a rotating rod 11 rotatably mounted on the mounting box 2. The rotating rod 11 is symmetrically fitted with two sets of sleeves 15 that are slidably connected to the mounting box 2. The inner wall of the sleeve 15 has a protrusion 1501, and the protrusion 1501 is slidably disposed in the fitting groove opened on the rotating rod 11.

[0034] The fitting groove includes a horizontal groove 1101 and a threaded groove 1102 formed on the rotating rod 11;

[0035] Specifically, please refer to Figure 5 , Figure 6 , Figure 7 The above-mentioned sleeve 15 is provided with a T-shaped block 1502, which is slidably disposed in the T-shaped groove opened on the mounting box 2. With the cooperation of the T-shaped block 1502 and the T-shaped groove, the sleeve 15 can only move along the axial direction of the rotating rod 11.

[0036] In the initial state, the cleaning component and the application component are close to each other. When the mounting base 5 drives the lens body 4 to rotate, the trigger component can drive the rotating rod 11 to rotate continuously in the same direction, so that the cleaning component and the application component move away from each other along the axial direction of the rotating rod 11 while maintaining contact with the surface of the lens body 4. This allows the application component to move outward in a spiral manner from the center of the lens body 4 to apply adhesive to the surface of the lens body 4.

[0037] Specifically, please refer to Figure 4 , Figure 5 , Figure 6 , Figure 7The cleaning component and the application component are respectively mounted on two sets of sleeves 15. The cleaning component includes a plug rod 20 fixedly connected to the sleeve 15. A second spring 21 is sleeved on the plug rod 20. One end of the second spring 21 abuts against the sleeve 15, and the other end abuts against a slider 16 slidably mounted on the plug rod 20. A scraper is mounted on the slider 16.

[0038] Specifically, the second spring 21 is always in a compressed state, pushing the slider 16 and the scraper away from the sleeve 15;

[0039] It should be noted that the scraper is a soft scraper, and with the cooperation of the second spring 21, the scraper can fully contact the lens body 4, thereby cleaning the surface of the lens body 4 which has curved characteristics, thus improving the adhesion of the subsequent adhesive and the clarity of the lens body 4 after the PET film is adhered, thereby extending the service life of the lens body 4.

[0040] The applicator includes a slide rod 18 disposed on another set of sleeve cylinders 15. A first spring 19 is sleeved on the slide rod 18. One end of the first spring 19 abuts against the sleeve cylinder 15, and the other end abuts against the glue injection cylinder 17 slidably disposed on the slide rod 18. An applicator roller brush 1701 is rotatably mounted on the glue injection cylinder 17.

[0041] In detail, the first spring 19 is always in a compressed state, pushing the glue injection cylinder 17 and the application roller brush 1701 away from the sleeve cylinder 15. The outer surface of the application roller brush 1701 is provided with a ring of soft bristles, which can absorb the adhesive in the glue injection cylinder 17. With the cooperation of the first spring 19, the application roller brush 1701 can maintain full contact with the surface of the lens body 4, thereby applying adhesive to the surface of the lens body 4. In the initial state, the height of the scraper is slightly lower than that of the application roller brush 1701.

[0042] Furthermore, please refer to Figures 1-5 The triggering component includes a linkage structure and a transmission structure. The linkage structure includes a drive gear 7 rotatably mounted on the lifting platform 3. The drive gear 7 meshes with a toothed structure 6 formed on the outer wall of the mounting base 5. In particular, the number of teeth in the toothed structure 6 is a multiple of the number of teeth in the drive gear 7, so that the transmission ratio between the drive gear 7 and the mounting base 5 is one to many. A fixed cylinder 8 is also coaxially arranged on the drive gear 7.

[0043] The transmission structure includes a transmission rod 9 rotatably mounted on the mounting box 2. The transmission rod 9 is inserted into the fixed cylinder 8 and is connected to a linkage rod 22 rotatably mounted on the mounting box 2. The linkage rod 22 is connected to the rotating rod 11 through a bevel gear set 13.

[0044] The bevel gear set 13 includes a first bevel gear and a second bevel gear. The first bevel gear is coaxially fixed with the linkage rod 22, and the second bevel gear is coaxially fixed with the rotating rod 11. The transmission rod 9 is connected to the linkage rod 22 through a toothed belt. In particular, the radius of the second bevel gear is multiple times that of the first bevel gear. Combined with the transmission ratio between the mounting base 5 and the drive gear 7, the transmission ratio between the mounting base 5 and the rotating rod 11 is one to one.

[0045] Specifically, please refer to Figure 4 Two sets of grooves 901 are equally spaced on the outer wall of the aforementioned transmission rod 9. The grooves 901 cooperate with the protrusions 801 provided on the fixed cylinder 8, so that the transmission rod 9 and the fixed cylinder 8 can only slide relative to each other.

[0046] In the initial state, the mounting base 5 is far from the mounting box 2. After the lens body 4 is placed stably, the control system of the base 1 is activated. Subsequently, the electric telescopic rod 10 pushes the lifting platform 3 and the mounting base 5 closer to the mounting box 2. When the lifting platform 3 rises to the designated position, the scraper first contacts the lens body 4. At this time, the sensor 201 set on the mounting box 2 sends a signal to the control system to drive the drive rod 12 to rotate the mounting base 5 clockwise (refer to...). Figure 1 describe);

[0047] Next, with the cooperation of the triggering component, the rotating rod 11 rotates synchronously with the mounting base 5. At the same time, the protrusion 1501 engages with the horizontal groove 1101, keeping the sleeve 15 stationary in its current position. As the mounting base 5 rotates, the scraper first cleans the lens body 4 until the electric telescopic rod 10 stops moving, at which point the lens body 4 comes into contact with the application roller brush 1701. At this time, the threaded groove 1102 engages with the protrusion 1501, and the application roller brush 1701 comes into contact with the cleaned lens body 4. As the mounting base 5 continues to rotate, the scraper and the application roller brush 1701 move away from each other with the cooperation of the protrusion 1501 and the threaded groove 1102, so that the scraper and the application roller brush 1701 spiral outward from the center of the lens body 4, completing the application of adhesive. Throughout the process, the scraper first cleans the lens body 4, and then the brush 1701 applies adhesive to the cleaned lens body 4. This sequential cleaning and application process increases the application speed of the adhesive and makes the application more uniform.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
